Mapping migration in low and middle income countries

Human mobility continues to increase in terms of volumes and reach, producing growing global connectivity. This connectivity hampers efforts to eliminate infectious diseases such as malaria through reintroductions of pathogens, and thus accounting for it becomes important in designing global, continental, regional, and national strategies. Recent works have shown that census-derived migration data provides a good proxy for internal connectivity, in terms of relative strengths of movement between administrative units, across temporal scales. To support global malaria eradication strategy efforts, an open access archive of estimated internal migration flows in endemic countries has been built through pooling of census microdata. These connectivity datasets are available both through the WorldPop website and the WorldPop Dataverse Repository.
